Estimate only — not tax advice. Built from the data you entered in the LedgerLine tools, using 2025 IRS figures (standard deduction, self-employment tax with the $176,100 Social Security cap, a simplified 20% QBI deduction, and an approximate state rate). Mileage uses the $0.70/mile standard rate; business meals are counted at 50%. W-2 wages and federal withholding (entered above) are folded in for employees, producing a refund-or-balance-due estimate; unreimbursed W-2 job expenses generally aren't federally deductible (2018–2025). Quarterly figures split your annual estimate evenly (÷4); the IRS also allows the annualized-income method, which can be lower early in the year. W-2 wages and the home-office deduction are single annual values applied to the selected year (not split by year). Your actual tax depends on your full return — credits, other household income, and deductions not tracked here. All data stays in your browser. Consult a qualified tax professional.
